To all whom t may' concern Be it known that I, JOHN E. GARRETT, a citizen of the Dominion of Canada, resident of New Glasgow, in the Province of Nova Scotia and Dominion of Canada, have made a certain new and useful Invention in Machine for Working Rugs; andfI declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which `form a part of this specification.

Figure 11 is a (fragmentary side'view of the invention, with the bars in partly advanced position. f

The invention has relation] to machines for working rugs or mats known as hooked or drawn-in rugs, havin a base of suitable fabric, such as burlap or lessian. This base is of the desired size, being either plain or having a pattern to be worked in the rug, .the edges being hemmed or bound and said fabric stretched tightly in a frame'made for the purpose. The material for working the rug may be yarn, or cloth torn into strips of suitable width for the purpose, said material e being worked through said fabric in the form .of loops until therug is finished, when none "ofthe fabric remains visible. v

In'thejuseof the old fashioned rug hook,

r`the worker draws the loops up throughthe fabric or base, toward the person, the loops 1n the present case, however, being pushed through the fabric, away from the person of the worker, the Vwork being done much more quickly and more evenly.

The invention is designed as an improvement over the device of the U. S. Patent No. 889,922, dated June 9, 1908, of the present applicant, having for its object to provide means for adjusting the height ofthe loop or to make loops of different height, whereby the thickness of the rug may be varied; to

provide means for varying the length of step by which the machine advances over the fabric or pattern, whereby the loops are made close together or farther a art, and to provide means admitting of t e use of needles of two or more sizes, whereby material or yarn of different sizes may be employed in working the rug. Other objects and advantages will hereinafter appear.

The invention consists in the novel construction and combination of parts, as hereinafter set forth.

In the accompanying drawings, illustrat ing the invention, the numeral 2 designates the main frame of the machine, formed of Hat or strap metal and provided at one end with a` knob vor handle 3.

Working longitudinally upon the main.

frame is the winged handle l1, the aperture 12 of which closely engages the marginal edges'of the main frame, said handle being provided with a longitudinal extension 32, parallel to and offset from the main frame.

The needle bar 13 is connected with said extension by screws 14, engaging and working in slots 15 of the extension, and is provided with a lug '17, extending through a slot 23 of the main frame. The end walls of said slot 23 serve to limit the throw of needle bar 13. An upset end 24 of lug 17 cooperates with the head of screw 16, lug, to hold the free end of the needle bar 1n proper relation to sai'dframe, this engage-- ment, together with the engagement of the aperture l2 with the frame, serving to maintain the handle extension 32 and needle bar 13 in parallel relation to the frame, and to prevent twisting movement of the winged handle with relation thereto.

A presser foot 4 is located at the outer end of the main frame, being secured thereto at its inner end at 25. The presser foot is made of spring metal, and extends at its inner portion parallel'to the main frame at 5; thence carried by said Ahas threaded engagement at 10 with the free end portion of the main frame. By adjustment. of this screw the presser' foot may be adjusted inwardly towards or allowed throughits inherent resiliency to withdraw from the main frame, whereby the angle of inclination of the part 6 of the presser foot shank to the main frame may be varied.

The needle bar lies outside of andjworks portion of its movement being taken up by movement of the screws 14 in the slots 15.

close to the longitudinal .stem or shank of the presser foot, and in the .latter portion of its outward stroke engages with the cam or inclined portion -6 ofsaid shank, thereby forcing the presser foot proper one step across the free end of the main frame, and across the fabric or pattern. Upon Ythe backward stroke of the winged handle the presser foot, through inherent elasticity,will automatically resume its normal position, ready for the next step of advance; or more properly stated, the presser foot takes a bearing on the goods or rug and restores the machine to normal position relative to itself, in shifted `position upon the rug. The adj ustment of the screw 9, aforesaid establishes the initial degree of inclination of the-cam portion of the longitudinal presser foot shank and the extent of projection of such camportion beyond the plane of the needle bar, and regulates the length of step of the presser foot.

The tubular lance or needle 14 has at its `rear end anPinturned lug 15 whereby it is connected, by screw 16, withlug 17 `of the or bore of the tubular needle, and at its rear.

end is connected by screw 19 with the looper bar 20, the latter having attachment screws 2.1 which work in longitudinal slots 22 of the main frame, the looper bar being thereby held close to the main frame, parallel to and against which it slides. The blade is moved in either direction through Contact of the winged handle with the head of one orthe.

other of the screws 21, and is held in either extreme position until this contact is effected by means of oppositely extending dogs 27, pivoted at 28 to.the main frame and having hooked ends 29 designed to engage the end walls of an upturned edge 30 of the looper bar, the dogs being held against Said edge by the action of spring 31. The aperture '12 of the winged handle has lateral extension at 33, to accommodate the looper bar and t-he dogs 27, and projecting into this aperture, between the edge 30 and the adjacent faces of the dogs, is a tooth 34 which, in the movement of the handle, act-s to lift said dogs from latching engagementv with the looper bar immediately before the engagement of the handle with the screws 21.

The parts being in normal' position, the winged handle 'is moved outwardly, the first the needle and needle bar being then moved outwardly, contact of the handle with will move togetherwith said handle, the,

looper bar moving a' distance equal to the length of the'slots 22, or until the looper blade has followed the needle through the goods to anextent which is constant in all cases. In other words, the handle first moves alone, next theneedle moves with the handle, and finally the looper moves with the handle and needle. During the initial movement of the needle slack is created in the yarn between the portion thereof held by the coils of spring 26 and the portion already looped into the fabric base, while during the final movement of the'needle the looper blade extends'this slack into a loop.

Upon reversal of the movement of the winged handle, the needle is first withdrawn lll) therewith, owing to the action of a spring 35, carried by-handle extension. 32 and having a bent outer end 36,v engaging the outer end of the needle bar. The reverse movement being continued, said bent end engages a cam surface 37 of a loop gauge 38, carriedv by the main frame. being thereby released from the needle bar, which will then become stationary during the second part of the return movement of the handle, being positively prevented from moving inwardly with the handle at this` Atime by a' spring 39 arried by the aforesaid loop gauge `and 'havy ing a bent inner end 40 engaging a shoulder 41 of the needle bar. Spring 39 is released from shoulder 41 at the end ofthis second part of the handle return movement by a cam surface 42 upon the handle extentraction of the needleobar.

sion 32 engaging said bent inner end of the spring, the outenwalls of slots 15 then acting upon the screws. 14 to complete the rey .The period'of release of the. needle bar from return movement with the handle is governed by the difference in extent of the interval between cam surface 37 and spring end 40 of the loop gauge and cam surface 42 and spring end 36 of the handle extension, and as said loop gauge is adjustable longitudinallyl of the main frame', by vmeans of a screw and slot connection 4:3 therewith, said period may occur sooner or later 'in the return movement of the handle.

, The looper remains in `the fabric base until the winged handle has returned sufi\ ciently to release thel looper latch and engage the inner screw 21, the point of en- 20l gagement with respect to this return movement being constant. Therefore, the needle willhave been returned more or less to normal retracted position before 'the looper starts its return movement, according tol the adj ustment ofthe loopgauge 38.

During the third part of the return move- 1- ment of the handle the needle and needle bar and the looper and looper bar move therewith. l case of extremeV adjustment inwardly oli2 the loop gauge 38.this thirdpart of movementiwill be very short, or scarcely perceptible. i

The loop of yarn will be held in the lfabric base during the initial retractive movement carried by saidv needle for withdrawinga portion ofyarn from the loop.

. 4.1In a machine for` working rugs having fabric bases, a reciprocatory needle, a reciprocatorylooper adapted to push a length of yarn outwardly through said base, and means -for imparting an invariable outward.

the yarn pullingthrough spring 26 of the needle, while during the final movement of tirsV -the needle, the looper blade being also retracted, the tension of spring 26 will act to pull out a given portion of said loop fromv the base. Therefore the height ofthe loops made in the goods lor fabric base is governed by the adjustment ofthe loop gauge, 38, whereby, as stated, the initial `and final return movements of the needle, withot and together with the looper blade, are varied in extent.
